经过我的寻找，我找到了一个较满意的答案，现在分享给论坛的兄弟姐妹们，不过这个代码有bug，也请高手过来帮我看看，完善一下代码：//toSolar()农历转成公历    toLunar()公历转成农历

//以上是农历公历的函数。

不过这里有个bug 就是公历的1900-1-1 转成农历为1989-12-5（没有问题）
                但是农历的1989-12-5转成公历却是：1989-13-1（有问题）
因此请高人过来帮我们修改修改，让我们学习学习一下。

上面写错了是就是公历的1990-1-1 转成农历为1989-12-5（没有问题）
但是农历的1989-12-5转成公历却是：1989-13-1（有问题）

经过学习，我发现农历这东西是没有算法的。要靠查表来实现。但是很奇怪的是：公历的1990-1-1 转成农历为1989-12-5（没有问题）
但是农历的1989-12-5转成公历却是：1989-13-1（有问题）请问上面的农历转公历的代码中哪里错了。求解释！

找到别外一个，不过有些错误的，请高手过来看看，并修改修改好吗？？？？

本程序中，公历转农历是网上找的，没有问题~~~
农历转公历时，如果本年不是闰年的话，也没有问题~~~~
但是，当那一年是闰年时，农历转公历算出来就不对！
但是我也不知道到底该咋改~~~
请大家帮我看看~~~多谢了~~~
